Claims.

This invention relates, as indicated, to means for ventilatingautomobiles, but has reference more particularly to a novel window andshutter arrangement for accomplishing such ventilation, and to novelmeans for raising and lowering the window as well as for preventingunauthorized attempts to open the window.

A primary object of the invention is to provide ventilating means of thecharacter described which can be easily and quickly installed on anautomobile, and which, when installed, can be arranged and adjusted toprovides. wide variety of ventilating efiects, without, in most cases,permitting entry of rain, dust and dirt into the automobile.

Another object of the invention is to provide ventilating means of thecharacter described, which is of simple design and inexpensive tomanufacture, and which requires little or no servicing to maintain ineffective operating conventilating means of the character described, em-

bodying a novel window elevating and lowering mechanism.

A still further object of the invention is to provide ventilating meansof the character described embodying means for preventing unauthorizedattempts to lower the window, so as to prevent access to the interior ofthe automobile by unauthorized individuals.

A still further object of the invention is to provide means forpermitting the window to rock laterally so as to compensate forout-of-square conditions and misalignment, as well as to resist breakageor damage in the event that the ,window is accidentally pushed laterallyto an undue extent.

Other objects and advantages of the invention will be apparent duringthe course of the following description:

Fig. 13 is a view similar to Fig. 4, but showing a modified form ofshutter operating mechanism, and

Fig. 14 is a view similar to Figs. 1 and 10, but showing a modified formof window locking mechanism.

Referring more particularly to Figs. 1 to 12 inclusive, there isillustrated a car door I of more or less conventional form, and having awindow opening 2, the front edge 3 of such opening sloping downwardlyand forwardly, in accordance with conventional construction.

The door I is provided with a window 4 which, in outline, conformsgenerally with the shape of the window opening, and has a front edge 5which is substantially parallel with the edge 3 of the window opening,it being noted that the portion of the door frame, which has the windowopening, is recessed as at 6 (Fig. 3) for the reception of the edge 5 ofthe window when the window is in fully closed position.

In order to provide a desired type of no-draft ventilation for theautomobile, a glass shutter I is provided, which extends substantiallyparallel with the edge 3 of the window opening 2, and has secured to itsupper edge a metallic holder 8 (Fig. 2) of channel-shaped cross-sectionhaving an embossment 9 struck therefrom to provide a pivot point forentry into a corresponding conical seat I0 in the door frame. Theshutter I has secured to its lower end a metallic holder ll ofchannel-shaped cross-section, to the lower face of which a worm gear I2is secured, preferably by welding. A set screw l3 extends through thedoor frame and axially into the worm gear I 2, so that the shutter I maybe rotated about an axis which passes through the center of the conicalseat Ill and the center of the set screw I3.

For the purpose of thus rotating the shutter 1, a worm I4 is providedwhich is in mesh with the amasss sleeve bearing I5 which is mounted inand extends transversely of the door frame. The worm gear shaft extendsinto the interior of the car, as shown in Fig. 4, and is adapted to berotated by means of a crank handle IS. The worm and worm gear areenclosed in a suitable housing 11 having a removable cover i8, removalof which permits access to the worm and worm gear for replacementpurposes or for oiling or greasing these parts.

When in the closed position, shown in Figs. 1, 2 and 3, the glassshutter fits into a rabbeted opening l9 in the door, precluding entry ofdirt and water into the joint between the shutter and the door.

With the shutter 1 closed and the window 4 partially open, a suction iscreated by the movement of the car, drawing foul air from the interiorof the car.

With the shutter closed and the window opened to a reater extent, amoderate positive ventilation of the car is efiected.

With the window 4 partially open and the shutter open, as indicated bythe dotted lines in Fig. 3, a direct breeze or ventilating effect withinthe car is produced.

In all cases in which the shutter is in closed position, a desiredventilation of the car may be effected without permitting rain to enterthe car, a condition which is difilcult to obtain with present-dayventilating features on automobiles. In this connection it may be notedin Fig. 1 that the portion of the door panel at the upper left corner ofthe door has been so modified that the front edge 5 of the window 4 canbe opened to a substantial extent before the upper left corner portionof the window clears the door panel. This permits a desired ventilation,while precluding any possibility of rain entering the car.

It will be noted that the glass shutter l is so mounted, that byunscrewing the set screw it, the shutter may be removed from the doorfor replacement purposes. This is an important feature of the invention.

The window 4 has its bottom edge enclosed in a channel strip 20, towhich is spot welded,'

adjacent its forward end, a pair of longitudinallyspaced clips 2| ofgenerally U-shaped cross-section and having metallic blocks 22 rigidlysecured therein adjacent the bases thereof. These clips normally rest onthe horizontal flange 25 of a plate or bracket 24, a portion 25 of whichis in v the form of a segment of a gear, which is reinforced by means ofan arcuate member 26 having gear teeth aligned with the teeth of thesegment 25 of the plate 24.

The bracket or plate 24 is mounted for rotation or pivotal movementabout a stub shaft or pin 217, which is secured to a stamping 28 bymeans of a castellated nut 29, maintained against rotation by means of acotter pin 30,'which extends through the shaft and is normally disposedin one or the other of the radial slots in the head of the nut. Atension washer 3| is interposed between the head of the stub shaft 27and the bracket 24, and a fibre braking washer 32 is interposed betweenthe bracket 24 and the stamping 24. By this arrangement, the resistanceof the bracket 24 to pivotal movement about the shaft 21 may be adjustedin a desired manner.

For the purpose of rotating the bracket 24 about the shaft 21, so as tomove the window 4 to various positions, a pinion 33 is provided which isrigidly secured to a shaft 34 which is journalled in the stamping 28.The pinion 33 is in mesh with the gear segment 25, and may be rotated bymeans of a crank (not shown) which is accessible to the driver of thecar, being disposed on the inside of the door.

5 The window operating mechanism which has been described forms a unitwhich is mounted on the door frame within the hollow space of suchframe. By the use of such mechanism, the window 4 may be moved betweenthe extreme closed position shown in solid lines in Fig. 8 to the otherextreme position of movement indicated by the dotted lines in saidfigure. Throughout its downward movement, the window slides in afelt-lined channel 35 which is rigidly supported on the door frame, andis thus maintained against rattling at all times, and is protectedagainst shock.

To facilitate movement of the window 4 to its various positions, abalance spring 36 is provided, which is anchored at one end to thestamping 28, 20 and engages the channel strip 20 at approximately thecenter of such strip.

Means have also been provided for permitting the window 4 to rocklaterally about its mounting on the flange 23 of the bracket 24, so asto compensate for out-of-square conditions and misalignment, as well asto resist breakage or damage in the event the window is accidentallypushed laterally to an undue extent.

Such means is best shown in Figs. 1, 6, 10, 11 and 12, and includes lostmotion links or studs 31 which extend through slots 38 in the flange 23and are in threaded engagement with the blocks 22 in the clips 2|. Thestuds 37 have heads 39 between which and the flange 23 are interposedcompression springs 40. The slots 38 are sufllciently long to permit aslight degree of lateral movement of the studs so as to permit tiltingmovement of the window 4 to one side, as shown in Fig. 11, or to theopposite side as shown in Fig. 12, the flange 23 serving as a fulcrumduring such movement. Incidental to such tilting movement, the springs40 are slightly compressed, but upon release of pressure upon thewindow, the springs restore the window to the normal vertical positionshown in Fig. 6.

Means have also been provided for preventing or discouraging attempts toopen the window by a direct downward push upon the window, particularlyby persons or individuals who have not been authorized to gain access tothe interior of the car, such means being best shown in Figs. 1, 5 and10.

For this purpose, the stamping 28 is provided adjacent its upper endwith an arcuate slot 41,

which is concentric with the stud 21 and is provided at its upper edgewith ratchet teeth 42. The clip 2| at the forward end of the channelstrip 20 has welded or otherwise secured thereto a latch member 43having a downwardly and forwardly extending arm 44 which projects intothe space between the bracket 24 and stamping 28 and is provided with atooth or pawl 45 which extends into the slot 4 l When the window islowered in the normal way, as by rotating the shaft 34, the pawl 45merely rides upwardly in the slot 4| and does not in any way interferewith the operation of opening the window.

When, however, an attempt is made to force the window open by pressureapplied to the window in the manner indicated in Fig. 10, the rear clip2i will tend to rock in a counter-clockwise direction on the flange 23as viewed in Figs. 1 and .10, causing the springs 40 to be slightlycompressed, the spring under the forward clip being compressed to agreater extent than that under the rear clip, (see Fig. and permittingthe latch member 43 to be elevated to a slight extent, but sufficientlyto cause the upper end of the pawl or tooth 45 to engage one or theother of the ratchet teeth 42, thereby effectively looking tthe windowagainst further downward movemen This locking action is facilitated byvirtue of the friction which has been set up between the bracket 24 andstamping 28, and which permits the rocking movement which has beendescribed to be set up before such friction is overcome. The frictionbetween the bracket 24 and stamping 28 is constant, being maintainedthrough the use of the elements 29, 30, 3| and 32, which have beendescribed;

Referring now to Fig. 13, there is shown thereis shown therein amodification of the shutteroperating mechanism which permits all of theoperating parts to be housed in a conventional type door, without thenecessity of providing bulged-out parts to accommodate the operatingmechanism, as in Fig. 4. In this case, the shutter is mounted to rotateabout an axis 45 which is disposed within the space between the doorpanels, and is adapted to be rotated by means of a worm 41, through theintermediary of a worm gear 48 and a worm pinion 49, all of which partsare disposed within the confines of the door panels. Acess to theseparts for repair or replacement purposes may be had through an open ing(not shown) in the innerpanel 50 of the door.

Referring now to Fig. 14, there is disclosed therein a modification ofthe means for locking the window 4 to forestall opening thereof by adirect downward push. In this case, the channel strip 20 has weldedthereto a plate 5| having an arcuate edge 52. A trigger member 53 isprovided, which is pivoted as at 54 to the frame of the door 55, thistrigger member having gear teeth 56 which are in mesh with the teeth 25of the plate 24. The arcuate edge 52 is concentric with the pivotal axisof the trigger 53. The trigger 53 is provided with an arcuate edge 51which is spaced slightly from the edge 52 and is concentric with thelatter. 4

When the window 4 is lowered in the normal way, as by rotating the shaft34, the teeth 25 of the bracket 24, which are in mesh with the teeth 56of the trigger 53, will cause the trigger to rotate about its pivotedaxis 54, with the result that the arcuate edge 51 of the trigger willremain in uniformly spaced relation to the edge 52 of the plate 5|, sothat no interference is created with the operation of opening thewindow.

When, however, an attempt is made to force the window open by pressureapplied to the window in the manner indicated in Fig. 10, the windowwill rock on the bracket 24, as previously described in connection withFig. 10, and the plate 5| will be depressed sufficiently to cause theedge 52 thereof to engage the edge 51 of the trigger. This brings abouta wedging action between the plate 5| and the trigger, with the resultthat the teeth 56 and 25 become venting further downward movement of thewindow.

Although the aforesaid invention has been described particularly withreference to an automobile door, it will be understood that all or someof the features thereof may be incorporated in other parts of theautomobile body, as for example, in connection with the rear bodywindows.

This application is a continuation-in-part of my abandoned copendingapplication, Serial No. 531,317, filed April 1'7, 1944.

It is to be understood that the form of my invention, herewith shown anddescribed, is to be taken as a preferred example of the same, and thatvarious changes in the shape, size and arrangement of parts may beresorted to, without departing from the spirit of my invention, or thescope of the subjoined claims.
